As per my review, here, of the Hornby Bulleid Merchant Navy R3717 21c7 Aberdeen Commonwealth in SR wartime black, the model has been produced in her early condition, with the ‘widows peak’ without smoke deflectors. 21c7 was one of the first batch of ten Merchant Navy pacifics, she was introduced in June 1942 in malachite green livery but was quickly repainted in plain black as a wartime measure. 21c7 remained in this condition until August 1944 when she gained the more familiar cowl above the smokebox and also received short flared smoke deflectors. She gained the to become standard length and style of smoke detectors whilst still in black in June 1947.
As my usual modelling period is between 1946 and 1949 I have forward dated 21c7 to the condition she was just before being outshopped in malachite green at the end of June 1947. This requires the fitting of the cowl above the smokebox, in place of the ‘widows peak’, the fitting of standard smoke deflectors, with electric lamps attached. The middle position lamp irons were also moved to the smokebox door once smoke deflectors were fitted.
For this relatively simple forward dating process I have used the following items: etched smoke deflectors, electric lamps and a replacement smoke box dart from the excellent Albert Goodall range supplied by my friends at RT Models. The replacement lamp irons are simply staples cut to length and I have replaced the flat printed nameplates and smokebox door roundel with etched versions from Fox Transfers.
The Hornby nameplates come off quite easily, they are held in place by three small lugs, one in the centre and one towards each end of the arms. I slide a sharp knife underneath from one side to the other to lift the plates. I then ensure any remaining lug was carefully cut flush to the side. I affix the etched plates using a very small amount of superglue applied with a cocktail stick (some people prefer to use a small amount of varnish instead of glue).
The first step was to fold up and solder the brackets just below the top inside edge of the etched brass deflectors. The deflectors were then bent to both their correct vertical shape and also the curve at the bottom edge to match the existing fairing. I then used the deflectors to mark the position of the horizontal cut required in the existing front fairing. An Albert Goodall electric lamp was glued on the inside front edge of each deflector lining up with bottom of the two rivets on the outside of the deflector. I then used Halfords spray cans to first prime using etched primer before top coats of satin black.
Next I took a deep breath and using a razor saw, cut horizontally, along the previously marked lines, the fairing back to the smoke box face and then vertically downwards level with the smokebox front, this removes both the ‘widows peak and the sides to meet the horizontal cuts. I also removed the Hornby printed roundel and the smokebox door dart. The sides of the slot in front of the chimney was also filed to match the rest of the opening. With all cuts cleaned up with a fine file, I also bevelled the remaining front fairings to give them a thinner edge appearance.
The Albert Goodall cast white metal cowl was filed to suit the slot in front of the chimney and glued into place using superglue. I drilled holes in the smokebox door for the two lamp irons and the replacement door dart. The finish painted deflectors were glued into place with the top brackets affixed to the top edge of the flat top gutter strip.
The Hornby model as supplied has an all over slightly matt finish, in reality the flat top, cab room and middle section of the tender cab roof were matt, whilst the sides were more of a satin finish and the front cowl also tended to be satin. I repainted the top and the smokebox front and door matt black. Before applying the etched nameplates and roundel I masked the matt areas and sprayed the sides of the model with Halfords satin lacquer. Once the nameplates and roundel were fitted the final tasks were to fit the new Albert Goodall smokebox door dart and the Hornby supplied cylinder drain cocks.
Once you get over the brave step of putting a razor saw to a brand new model the modification is reasonably quick and easy to complete. I will at some stage do the same to my malachite green R3435 21C3 ‘Royal Mail’ model!

Does RT supply promptly now,
or did you have to wait a month for the parts?
Hi Mike, they arrived promptly as is my usual experience. Please bear in mind that Robert has a day job as well as RT Models and sometimes if an item is out of stock it will require a short wait before it is restocked.
You’ve made a smart job of it Graham, I don’t think I’m that brave on a new model! I’d have to keep it a while first. I bought 21C3 as I wanted an early version and have kits for the later ones. Tell me do you do anything about those flange less trailing wheels? I want to replace mine.
Best regards, Phil.
It looks brilliant
Looks great. I wonder if Hornby will get round to modelling this variant?
Could you clarify something about this conversion – did you feel the need to alter the tender?
I know that MN tenders are pretty complicated to research, but the Derry book on the MNs states that on the first series of tenders (i.e. those fitted to the first ten locomotives), the rave at the back of the tender (as modelled on Hornby’s models of 21C3 and 21C7 in as built condition) was not a feature of the tenders attached to 21C3 onwards, but was cut away. This logically should indicate that the Hornby tenders for these particular models are incorrect and therefore the rave needs to be cut down to suit?
It is very difficult to find tender first shots of the MNs pre 1948, so if you could clarify this matter for me then I would be very grateful.
Derry is correct and I do need to put the saw to my two tenders and amend them, I picked up the fact I had missed that detail after I initially did the conversions, and will correct them in due course.
